Ads Break-Even Calculator
Find the maximum CPA, maximum CPC and minimum CTR your campaign needs to break even. Works for Meta Ads, Google Ads and TikTok Ads. Includes conservative, neutral and aggressive scenarios plus implied ROAS per scenario.
Revenue & margin
Gross margin (after product cost and fees)
Visitors that become orders
Inventory (optional — to calculate minimum CTR)
Averages: Meta R$ 15-40, Google Display R$ 8-20
Averages: Meta 0.9-1.5%, Google Search 3-6%
Why use 3 scenarios
- Conservative (50%): leaves room for measurement errors and excluded operational costs.
- Neutral (75%): target for a healthy operation — bid goal.
- Aggressive (90%): only justified with high LTV or strong repeat purchases (covers day-1 loss).
Reading caveats
- • "Maximum" CPA assumes each sale only recovers the first-order margin. If you have strong repeat purchases, you can go higher.
- • The LP conversion rate must be real, not a market average. Use your own, from the quarter.
- • Compare CPM/CTR with effective ROAS after 1-2 weeks — the model is a projection, not a guarantee.
